Question

I know this is very basic question, but I need to know, how I can display the contents of a variable on the screen.

Do I use a textview in my layout?

I have a textview box and I can set it to say something in the editor but I need to write the contents of a variable so I can do some error checking.

Anyone help?

If you have a TextView named textViewName defined in your layout XML file, you can just do something like this in your Activity class:

setContentView(R.layout.layoutName);
TextView textView = (TextView) findViewById(R.id.textViewName);
textView.setText("text you want to display");

Is this what you’re looking for? If you don’t need to display it to the screen, and just want to debug, just use Log() and logcat to view the messages.
